The 18-year-old was admitted to Cedars Sinai Medical Center late Saturday night after she was carried on a stretcher by emergency service staff from the Beverly Hilton Hotel, where her mother died. She then returned to the hospital for a second time on Sunday morning.

A source tells People magazine that Bobbie Kristina was in the hotel lobby when her mother, who was found in the bathtub by a member of her entourage, was pronounced dead.
